DESCRIPTION OF THE RELATED ART

Yagi et al. (Yakugaku Zasshi. 2003 July; 123(7):517-32) reportcinnamoyl, p-coumaroyl, feruloyl, caffeoyl aloesin, and relatedcompounds that were isolated from Aloe species. The antiinflammatory andantioxidative activities of these compounds were examined based on thestructure-activity relationship. It was suggested that the bioactivitiesmight link to acyl ester groups in aloesin, together with those ofaloesin-related compounds. Investigations using the contacthypersensitivity response indicated a preventive effect of aloesin onthe UV-B-induced immune suppression. Furthermore, aloesin inhibitedtyrosine hydroxylase and dihydroxyphenylalanine (DOPA) oxidaseactivities of tyrosinase from normal human melanocyte cell lysates.These results show that aloesin prevents not only UV-B-induced immunesuppression, but also could be a positive pigment-altering agent forcosmetic application. In preclinical study, aloe extract wasinvestigated using phagocytosis and nitroblue tetrazolium chloride (NBT)reduction in adult bronchial asthma, and high molecular-weightmaterials, such as polysaccharide and glycoprotein fractions wereidentified as active ingredients. The neutral polysaccharides,aloemannan and acemannan showed antitumor, antiinflammatory andimmunosuppressive activities, and glycoprotein fractions withbradykinindegrading and cell proliferation-stimulating activities wereidentified from the nondialysate fraction of the gel part of Aloespecies. Verectin fractionated from Aloe vera gel was examinedbiochemically and immunochemically, and verectin antibody was used inthe appraisal of commercial Aloe vera gel products. It was reported thataloesin stimulates the proliferation of cultured human hepatoma SK-Hep 1cells. Thus aloesin, related compounds, and high molecular-weightmaterials, such as aloemannan and verectin, may act in concert to exerttherapeutic properties for wounds, burns and inflammation.

Yagi et al. (Planta Med. 2002 November; 68(11):957-60) antioxidantcomponents in Aloe vera that were examined for lipid peroxidation usingrat liver microsomal and mitochondrial enzymes. Among the aloesinderivatives examined, isorabaichromone showed a potent antioxidativeactivity. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical andsuperoxide anion scavenging activities were determined. As one of themost potent components, isorabaichromone together with feruloylaloesinand p-coumaroylaloesin showed potent DPPH radical and superoxide anionscavenging activities. Electron spin resonance (ESR) using the spintrapping method suggested that the potent superoxide anion scavengingactivity of isorabaichromone might have been due to its caffeoyl group.As A. vera has long been used to promote wound healing, the inhibitoryeffects of aloesin derivatives for cyclooxygenase (Cox)-2 andthromboxane (Tx) A 2 synthase were examined and the participation ofp-coumaroyl and feruloyl ester groups in the aloesin skeleton wasdemonstrated. These findings may explain, at least in part, the woundhealing effects of A. vera.

Chithra et al. (J Ethnopharmacol. 1998 January; 59(3):195-201) reportthe positive influence of Aloe vera, a tropical cactus, on the healingof full-thickness wounds in diabetic rats is reported. Full-thicknessexcision/incision wounds were created on the back of rats, and treatedeither by topical application on the wound surface or by oraladministration of the Aloe vera gel to the rat. Wound granulationtissues were removed on various days and the collagen, hexosamine, totalprotein and DNA contents were determined, in addition to the rates ofwound contraction and period of epithelialization. Measurements oftensile strength were made on treated/untreated incision wounds. Theresults indicated that Aloe vera treatment of wounds in diabetic ratsmight enhance the process of wound healing by influencing phases such asinflammation, fibroplasia, collagen synthesis and maturation, and woundcontraction.

Kim et al. (J Ethnopharmacol. 2010 Nov. 11; 132(2):529-32. Epub 2010Sep. 15) report that Aloe vera modulates immunological responses inatopic dermatitis, mainly through influencing IL-5 or IL-10 levels.

Yim et al. (Exp Parasitol. 2010 Aug. 17) disclose that Aloe vera couldbe used an alternative treatment for controlling avian coccidiosis.

Cowan (Br J Community Nurs. 2010 June; 15(6):280-2) reports Aloe veracould be used in the treatment of chronic non-cancer pain, particularlythat caused by osteoarthritis.

Yang et al. (Zhonghua Zheng Xing Wai Ke Za Zhi. 2008 January;24(1):50-3) report the effect of aloesin on melanocytes in the pigmentedskin equivalent model and showed an inhibition effect on the tyrosinaseactivity of melanocytes and reduced significantly melanin content in thepigmented skin equivalent mode.

Wang et al. (Int J Cosmet Sci. 2008 April; 30(2):121-30) showed thataloesin had direct inhibitory effects on melanogenesis and showeddose-dependent reductions in tyrosinase activity and melanin content.

Jones et al. (Pigment Cell Res. 2002 October; 15(5):335-40) report thataloesin inhibits purified tyrosinase enzyme and specifically inhibitsmelanin production in vitro. Enzyme kinetics studies using normal humanmelanocyte cell lysates and cell-based melanin production demonstratedthat aloesin is a competitive inhibitor of tyrosinase from mushroom,human and murine sources. Tyrosine hydroxylase and3,4-dihydroxyphenylalanine (DOPA) oxidase activities of tyrosinase fromnormal human melanocyte cell lysates were inhibited by aloesin in a dosedependent manner. In a percutaneous absorption study a finite dose ofaloesin penetrated the skin slowly and was recovered primarily in thesurface wash. Aloesin shows promise as a pigmentation-altering agent forcosmetic or therapeutic applications.

DETAILED DESCRIPTION

Water is a key element for life. However, some organisms have evolved anamazing adaptation (osmoprotection) that allows them to survive undercomplete dehydration conditions for months or years, until water ispresent again, at which time they resume their metabolism and growth.Anhydrobiosis (“life without water”) is found throughout all biologicaldomains, for example in several species of eubacteria, archea, somefungi, certain invertebrate species and “resurrection plants”.Osmoprotective agents act through compatible solutes to prevent cellulardamage. Osmoprotection has recently been recognized as a new therapeuticmethodology (Messmer, Ophthalmologe. 2007 November; 104(11):987-90).Osmoprotective agents act through compatible solutes to prevent—at leastin theory—a hyperosmolar condition from damaging the cellular function.

Cells must maintain an optimal balance of water to stay plump andhealthy. Imagine a face drawn on a balloon and filled with water. Theface will look plump and youthful as the water keeps pressure on theballoon's inside surface. But if the water were to slowly leak (osmosis)out of the balloon, the drawn face would increasingly look wrinkled,tired, saggy, and aged.

There are several reports suggesting that hyperosmolarity inducesinflammation. Schwartz et al., (J Inflamm (Lond). 2009 Jun. 23; 6:21)have shown that there is a the link between hyperosmolarity andinflammation by assessing osmolarity values in vivo during inflammationand compared the inflammatory potential of different osmotic agents andstudied the long-term consequences of hyperosmolarity on cell fate. Theexposure of cells to the different compounds, whatever their molecularweight, has no effect on the secretion of cytokines as long as theosmolarity is below a threshold of 300 mOsm. Higher osmolarities resultin the secretion of proinflammatory cytokines (Interleukin-8,Interleukin-6, Interleukin-1 beta and Tumor Necrosis factor-alpha).

Abolhassani et al. (Inflamm Res. 2008 September; 57(9):419-29) reportthat hyperosmolarity can induce pro-inflammatory cytokine responses.Inflammation appears to be the simple consequence of a shift ofmethylation of Protein Phosphatase 2A, which in turn activates Nuclearfactor-kappa B (NF-kappaB). The production of inflammatory cytokinescauses the acceleration of aging process.

Sarkar et al. (Cancer Lett. 2006 May 8; 236(1):13-23. Epub 2005 Jun. 22)report that a direct relationship exists between aging and increasingincidences of chronic diseases. In fact, with most age-associateddiseases individuals manifest an underlying chronic inflammatory stateas evidenced by local infiltration of inflammatory cells, such asmacrophages, and higher circulatory levels of pro-inflammatorycytokines, complement components and adhesion molecules. Consequently,treatment with anti-inflammatory agents provide symptomatic relief toseveral aging-associated diseases, even as remote as Alzheimer's orParkinson's disease, indicating that chronic inflammation may play asubstantial role in the pathogenesis of these disease states. Themolecular mechanisms underlying this chronic inflammatory conditionduring cellular senescence is presently unclear. Cellular damage byoxygen free radicals is a primary driving force for aging and increasedactivation of redox-regulated transcription factors, such as NF-kappaBthat regulate the expression of pro-inflammatory molecules, has beendocumented in aged animals/individuals versus their young counterparts.Human polynucleotide phosphorylase (hPNPase (old-35)), a RNA degradationenzyme shown to be upregulated during differentiation and cellularsenescence, may represent a molecular link between aging and itsassociated inflammation. HPNPase (old-35) promotes reactive oxygenspecies (ROS) production, activates the NF-kappaB pathway and initiatesthe production of pro-inflammatory cytokines, such as IL-6 and IL-8. Inthese contexts, inhibition of hPNPase (old-35) may represent a novelmolecular target for intervening in aging-associated chronic diseases.

Chambers et al. (J Clin Invest. 1987 March; 79(3):731-7) disclose thathuman urine is osmoprotective for enteric bacteria, permitting E. colito grow with high concentrations of NaCl and other salts and even higherconcentrations of sucrose and mannitol but not urea. Two majorosmoprotective compounds in urine have been identified: glycine betaine,and proline betaine. The presence of glycine and proline betaines inhuman urine may reflect an osmoprotective role for the kidney.

Chambers et al. (J Bacteriol. 1987 October; 169(10):4845-7) furtherreport that glycine betaine is believed to be the most active naturallyoccurring osmoprotectant molecule for Escherichia coli and otherbacteria. It is a dipolar ion possessing a quaternary ammonimum groupand a carboxylic acid group. To examine the molecular requirements forosmoprotective activity, dimethylthetin was compared with glycinebetaine. Dimethylthetin is identical to glycine betaine except forsubstitution of dimethyl sulfonium for the quaternary nitrogen group.Dimethylthetin was found to be about equally as effective as glycinebetaine in permitting E. coli to grow in hypertonic NaCl, and bothcompounds were recovered almost completely from bacterial cells grown inthe presence of hypertonic NaCl. 3-Dimethylsulfonioproprionate, ananalog of dimethylthetin observed in marine algae, and3-Dimethylsulfonio-2-methylproprionate was found to be less active.Dimethylthetin may prove useful as a molecular probe to study betainemetabolism and as a model for the development of antibacterial agents.

In modern medicine dry eye syndrome is one of the most common disordersencountered in daily ophthalmological practice. Hyperosmolarity of thetear film is one of the key pathogenetic factors in the development of acommonly subclinical inflammation of the ocular surface, the lacrimalgland and the tear film in dry eye syndrome. Osmoprotective agentsprevent a hyperosmolar tear film from damaging the ocular surface.

The agents that are known to provide osmoprotection in non-mammalianorganisms and plants include trehalose, maltose, sucrose, palatinose,cellobiose, gentiobiose, turanose, sorbitol, calcium chloride, certainamino acids (such as proline and alpha-glutamate),alpha-D-mannopyranosyl-(1-->2)-alpha-D-glucopyranosyl-(1-->2)-glycerate,Di-myo-inositol 1,1′-phosphate, N(gamma)-acetyl-2,4-diaminobutyrate(NADA), ectoine, glycine betaine, carnitine, pipecolic acid,dimethylsulfoniopropionate, dimethylsulfonioacetate, peptones, taurine,and taltrimide.

While use of humectants and emollients has been a common practice, theapplication of osmoprotection in skin and hair care of mammals has sofar been practically unknown.

Rosas-Rodriguez et al (Life Sci. 2010 Oct. 23; 87(17-18):515-20; Epub2010 Aug. 18) report enzymes involved in osmolyte synthesis, especiallyhow does oxidative stress affect osmoregulation in renal cells. Kidneymedulla cells are exposed to a wide range of changes in the ionic andosmotic composition of their environment as a consequence of the urineconcentrating mechanism. During antidiuresis NaCl and ureaconcentrations increase and an efficient urinary concentrating mechanismis accompanied by medullar hypoxia. Medullar hypotonicity increasesreactive oxygen species, a byproduct of mitochondria during ATPproduction. High intracellular ionic strength, hypoxia and elevated ROSconcentration would have deleterious effects on medulla cell function.Medulla cells respond to hypertonicity by accumulating organicosmolytes, such as glycine betaine, glycerophosphorylcholine, sorbitol,inositol, and taurine, the main functions of which are osmoregulationand osmoprotection.

Sagot et al. (Proc Natl Acad Sci USA. 2010 Jul. 13; 107(28):12652-7;Epub 2010 Jun. 22) report the dipeptide N-acetylglutaminylglutamineamide that was discovered in the bacterium Sinorhizobium meliloti grownat high osmolarity, and subsequently shown to be synthesized andaccumulated by a few osmotically challenged bacteria.

Gouffi et al. (Int J Food Microbiol. 2000 Apr. 10; 55(1-3):171-4; JBacteriol. 1998 October; 180(19):5044-51) report sucrose, trehalose,maltose, cellobiose, gentiobiose, turanose and palatinose are veryunusual osmoprotectants for Sinorhizobium meliloti, because thesecompounds, unlike other bacterial osmoprotectants, do not accumulate ascytosolic osmolytes in salt-stressed S. meliloti cells. Rather, thesecompounds were catabolized during early exponential growth, andcontributed to enhance the cytosolic levels of the two endogenouslysynthesized osmolytes: glutamate and the dipeptideN-acetylglutaminylglutamine amide.

Talibart et al. (Appl Environ Microbiol. 1997 December; 63(12):4657-63)report the fate of exogenously supplied glycine betaine and the dynamicsof endogenous osmolytes that were investigated throughout the growthcycle of salt-stressed cultures of strains of Sinorhizobium meliloti,which differ in their ability to use glycine betaine as a growthsubstrate, but not as an osmoprotectant. Glycine betaine is onlytransiently accumulated as a cytoplasmic osmolyte, which virtuallyprevents the accumulation of endogenous osmolytes during the lag andearly exponential phases of growth. Then, betaine levels in stressedcells decrease abruptly during the second half of the exponential phase.At this stage, the levels of glutamate and the dipeptideN-acetylglutaminylglutamine amide increase sharply so that the twoendogenous solutes supplant glycine betaine in the ageing culture, inwhich it becomes a minor osmolyte because it is progressivelycatabolized. Ultimately, glycine betaine disappears when stressed cellsreach the stationary phase.

Dominguez-Ferrera et al. (J Bacteriol. 2009 December; 191(24):7490-9;Epub 2009 Oct. 16) report the disaccharide trehalose is a well-knownosmoprotectant, and trehalose accumulation through de novo biosynthesisis a common response of bacteria to abiotic stress.

Perez-Arellano et al. (Extremophiles. 2010 July; 14(4):409-15. Epub 2010Jun. 11) report glutamate kinase, an enzyme involved in osmoprotectionin plants and microorganisms, catalyses the first and controlling stepof proline biosynthesis.

Lynch et al. (Biomaterials. 2010 August; 31(23):6096-103. Epub 2010 May14) report a biopolymer that has been shown to facilitate efficientdelivery of trehalose, a bioprotectant normally impermeable to thephospholipid bilayer, into ovine erythrocytes. Cellular uptake oftrehalose was found to be dependent on polymer pendant amino acid typeand degree of grafting, polymer concentration, pH, external trehaloseconcentration, incubation temperature and time.

Flanagan et al. (Nutr Metab (Lond). 2010 Apr. 16; 7:30) report topicalapplication of carnitine in dry eye offers osmoprotection and modulatesimmune and inflammatory responses.

Kitko et al. (PLoS One. 2010 Apr. 8; 5(4):e10078) report diverseosmolytes including NaCl, KCl, proline, or sucrose contribute tocytoplasmic pH homeostasis in E. coli, and increase the recovery fromrapid acid shift. Osmolytes other than K+ restore partial pH homeostasisin a strain deleted for K+ transport.

Iturriaga et al (Int J Mol Sci. 2009 Sep. 1; 10(9):3793-810) reporttrehalose, a non-reducing disaccharide, that is widely distributed inNature and has been isolated from certain species of bacteria, fungi,invertebrates and plants that are capable of surviving in a dehydratedstate for months or years and subsequently being revived after a fewhours of being in contact with water. This disaccharide has manybiotechnological applications, as its physicochemical properties allowit to be used to preserve foods, enzymes, vaccines, cells etc., in adehydrated state at room temperature.

Jorge et al (FEBS J. 2007 June; 274(12):3120-7. Epub 2007 May 22) reportthe discovery of a new solute, whose structure was established asalpha-D-mannopyranosyl-(1-->2)-alpha-D-glucopyranosyl-(1-->2)-glycerate(MGG). The level of MGG increased notably with the salinity of thegrowth medium up to the optimum NaCl concentration. At higher NaClconcentrations, however, the level of MGG decreased, whereas the levelsof proline and alpha-glutamate increased about five-fold and 10-fold,respectively. MGG plays a role during low-level osmotic adaptation ofPetrotoga miotherma, whereas alpha-glutamate and, to a lesser extent,proline are used for osmoprotection under salt stress. Fernandez et al(J Bacteriol. 2010 March; 192(6):1624-33. Epub 2010 Jan. 8) report thatmannosylglucosylglycerate (MGG), recently identified in Petrotogamiotherma, also accumulates in Petrotoga mobilis in response tohyperosmotic conditions and supraoptimal growth temperatures.

Jung et al (J Membr Biol. 2006; 213(2):119-33. Epub 2007 Apr. 6) reportamino acid transport is a ubiquitous phenomenon and serves a variety offunctions in prokaryotes, including supply of carbon and nitrogen forcatabolic and anabolic processes, pH homeostasis, osmoprotection,virulence, detoxification, signal transduction and generation ofelectrochemical ion gradients.

Garcia-Estepa et al. (Syst Appl Microbiol. 2006 December; 29(8):626-33.Epub 2006 Feb. 15) report N(gamma)-acetyl-2,4-diaminobutyrate (NADA),the precursor of the compatible solute ectoine, to function as anosmoprotectant for the non-halophilic bacterium Salmonella entericaserovar Typhimurium.

Pintsch et al. (BMC Biochemistry 2002, 3:10) have shown that cellssteadily face changes of the external osmolarity, to which they have toadapt. To withstand a steep increase in osmolarity, eukaryotic cellsactivate responses like “regulatory volume increase”, accumulation ofcompatible osmolytes and stimulated expression of stress proteins.Recently, an exception from this scheme has been identified:Dictyostelium cells protect themselves against hyperosmolarity bylargely rearranging cellular proteins, whereas no “regulatory volumeincrease”, no accumulation of compatible osmolytes and no change of theexpression pattern of the most abundant proteins were observed. Amongthe translocated proteins identified, cytoskeletal proteins appear to bepredominant. In particular, the rearrangement of actin and myosin II tothe cell cortex beneath the plasma membrane was shown to constitute apivotal element of osmoprotection in Dictyostelium. In this process thedistribution of the actin-associated protein Hisactophilin (a histidinerich; 31 histidine out of 118 amino acids) actin binding protein fromDictyostelium discoideum was investigated in order to gain a betterinsight into osmo-protective mechanism of the cell. Hisactophilin wasfound to be enriched in the cytoskeletal fraction of wild type cellsexposed to hyperosmotic stress. Hisactophilin is both translocated tothe cytoskeleton and phosphorylated during hyperosmotic stress inDicytostelium.

The present invention discloses certain derivatives of aloesin withamino acids, peptides, and amino sugars (formula I: a, b), and isomersand salts thereof;

The present invention also discloses a method of topical or oralapplication of said derivatives. This method can include a base, acarrier, or a delivery system. This method provides the treatment ofinfections and topical ailments in mammals including acne, rosacea,topical wounds, infections, dandruff, skin disfigurements, age spots,wrinkles, excess facial oil, and darkened skin.

Aloesin derivatives of the present invention have now been prepared by anovel method. A mixture of aloesin, an amino acid, a peptide, or anamino sugar, and a liquid medium is heated with mixing. An organic orinorganic base may also be included.

The amino acid used in the present invention can be any amino acid, suchas an alpha, beta, gamma, delta or other substituted amino acid. Thereaction of aloesin with an alpha amino acid, for example glycine,results in the formation of two possible geometric isomers, [formula II;(a) and (b)];

When an amino acid or a carboxy-terminal peptide is used, this reactionis accelerated by the inclusion of a mono- or divalent metal oxide,metal hydroxide, metal carbonate, or metal bicarbonate in equimolaramount, in which case the monovalent salt of said derivative is formed.For example, the reaction of aloesin with carnosine, a dipeptide, in thepresence of sodium bicarbonate proceeds to form formula (III) andisomers;

The reaction of aloesin with a dipeptide amide, for exampleosmoprotectant glutamylglutamine amide, forms isomeric compounds offormula (IV);

The reaction of aloesin with a dipeptide amide, for exampleosmoprotectant dipeptide alpha-glutamate, forms isomeric compounds offormula (V);

The reaction of an amide or ester derivative of an amino acid or acarboxy-terminal peptide, for example, the reaction of aloesin with4-hyrdoxyphenylglycine or its carboxy-terminal derivatives, results inthe formation of formula (VI), and isomers thereof.Hydroxyphenylglycines have become of much interest due to theirstructural presence in many macrolide antibiotics and syntheticpenicillins, for example vancomycin, helvecardin A, chloropolysporins,avoparcin, Ristomycic, and teicoplanin; 4-hydroxy- and3,5-dihydroxyphenylglycine are of special interest in that regard;

The amino acids and peptides, and their derivatives such as amides andesters and optical isomers thereof suitable for reaction with aloesinare of formula (VII);

Wherein,

R²═OR³, NR³R⁴, and peptide; and    -   iii. R³, R⁴═H, alkyl, and aryl; and    -   iv. n=0 to 10:        The examples include, among others, alanine, anthranilic acid,        arginine, asparagine, aspartic acid, cysteine, cystine, dopa        (mucuna prurience extract), glutamic acid, glutamine, glycine,        histidine, 3-hydroxyphenylglycine, isoleusine, leusine, lysine,        methionine, phenylalanine, phenylglycine,        4-hydroxyphenylglycine, 2-hydroxyphenylglycine,        2,4-dihydroxyphenylglycine, 3,4-dihydroxyphenylglycine,        3,5-dihydroxyphenylglycine, 2,4,6-trihydroxyphenylglycine,        proline, serine, threonine, tryptophan, tyrosine, valine,        selenocystein, pyrrolysine, mimosine, carnosine, carcinine,        glutathione, dipeptide-2, tripeptide-3, tripeptide-1,        tripeptide-5, pentapeptide-3, pentapeptide-4, tetrapeptide-7,        hexapeptide-3, octapeptide-3, hexapeptide-10, antioxidant        peptide a, antioxidant peptide b, cyclopeptide-2,        cyclopeptide-3, cyclopeptide-4, cyclopeptide-5,        glutamylglutamine, glutamylglutamine amide, alpha-glutamate, and        cyclopeptide-6.

The reaction of aloesin with an amino sugar or an inorganic acid salt ofsaid amino sugar, for example glucosamine hydrochloride, providesformula (VIII); an inorganic base is also included when inorganic acidsalt of an amino sugar is used to neutralize said salt-forming acid;

The reaction of aloesin with an amino sugar having a hydroxy substituentadjacent to nitrogen, the hydrogen bonding provides additionalstructural stability, as shown in formula (IX);

The amino sugars suitable for reaction with aloesin include, amongothers, glucosamine, galactosamine (chondrosamine), ribamine,allosamine, altrosamine, gulosamine, idosamine, talosamine, ribosamine,arabinosamine, xylosamine, lyxosamine, fructosamine, neuraminic acid(sialic acid), mannosamine, and their optical isomers.

The reaction of a β-amino acid, such as anthranilic acid, with aloesinprovides compound of formula (X) and isomers thereof. The hydrogenbonding provides additional structural stability;

The reaction of aloesin with a diamine, for example osmoprotective2,4-diaminobutyric acid, can form either a 1:1 reaction product (XI a),or a 2:1 reaction product (XI b), or a mixture of both and isomersthereof;

The reaction of aloesin with a divalent or polyvalent metal salt of anamino acid or peptide leads to the formation of dimers and polymers, forexample the reaction of aloesin with zinc glycinate produces dimericcompound in formula (XII) and isomers thereof. Other suitable metals forsalt formation include Li, Na, K, Ca, Mg, Ti, V, Cr, Mn, Fe, Co, Ni, Cu,and Se;

While the compounds of the present invention possess their own highbiological activity, upon penetration into skin these compounds canundergo chemical reversion to release original agents, for examplealoesine and glutamylglutamine amide in formula (XIII);

It is both surprising and unexpected that compounds of the presentinvention cause an improvement of skin condition such as acne androsacea, and dark spots and topical wounds. Although aloesin has beendisclosed to have antibacterial benefits, it is also well known thatthere are thousands of other antibacterial agents known to science allof which do not also cause a treatment or improvement of skin conditionsuch as acne, or rosacea, or dark spots, or topical wounds. Thus, merelybeing an antibacterial agent does not cause an ingredient or compositionto also cause a treatment or improvement of skin condition such as acne,rosacea, dark spots, or topical wounds.

Acne, Rosacea, and Facial Oil Control Benefits.

Acne is caused by a combination of several factors. In a previousdisclosure (U.S. patent application Ser. No. 10/248,691; filed Feb. 10,2003; now abandoned) the present inventor has discussed that acne is agroup of diseases whose initial pathology is the comedo and includesacne vulgaris, neonatal acne, infantile acne, and pomade acne. There areapproximately 45 million people who suffer from acne in America alone.The disease is so common in youth at their puberty that it often hasbeen termed physiological. Although acne stops appearing for most peopleby the age of 25, some people, the majority of them are women,experience the disease well into their adult life. This “adult acne”differs from teenage acne in location and that it tends to be moreinflammatory with fewer comedones. As the human concern for facialbeauty continues to receive heightened marketing attention, the cure forvarious forms of acne has received much attention, as evidenced by thenumber of patents and patent applications that have appeared recently.The patent literature abounds with acne treatments. From January 2001 toJanuary 2003 time period over 900 patent applications were published inU.S. patent applications computer database search that related to acne.From 1975 to January 2003, there were over 9000 patents issued by theU.S. Patents Office that had some reference to acne. From these data, itwould become obvious that a suitable solution to this problem has eludedpast efforts.

The disease of acne is characterized by a great variety of clinicallesions. Although one type of lesion may be predominant (typically thecomedo), close observation usually reveals the presence of several typesof lesions (comedones, pustules, papules, and/or nodules). The lesionscan be either non-inflammatory or, more typically, inflammatory. Inaddition to lesions, patients may have, as the result of lesions, scarsof varying size. The fully developed, open comedo (i.e., a plug of driedsebum in a skin pore) is not usually the site of inflammatory changes,unless the patient traumatizes it. The developing microcomedo and theclosed comedo are the major sites for the development of inflammatorylesions. Because the skin is always trying to repair itself, sheaths ofcells will grow out from the epidermis (forming appendageal structures)in an attempt to encapsulate the inflammatory reaction. Thisencapsulation is often incomplete and further rupture of the lesiontypically occurs, leading to multi-channeled tracts as can be seen inmany acne scars.

In general, there are four major principles presently governing thetherapy of acne: (i) correction of the altered pattern of follicularkeratinization; (ii) decrease sebaceous gland activity; (iii) decreasethe follicular bacterial population (especially P. acnes) and inhibitthe production of extra cellular inflammatory products through theinhibition of these microorganisms; and (iv) produce ananti-inflammatory effect. Acne is a chronic inflammatory diseaseaffecting the sebaceous glands. Acne lesions primarily involve thesebaceous glands located on the face, neck, chest and back. Both closedcomedones (blackheads) and open comedones (whiteheads) are caused byhyperkeratinization of the infundibulum of the sebaceous duct. Thesekeratinous plugs block the flow of sebum. These dilated ducts aboundwith the colonies of Propionibacterium acnes and other fat splittingorganisms. The clinically evident open and closed comedones and themicroscopic microcomedo are the signal lesions of acne. The acne processresults from a cascade of events. First, at puberty a spike in androgenproduction heralds an increase in sebum production and begins thehyperkeratinization process causing microcomedones and sebum blockade.With this blockage, the number of resident follicular flora increasesdramatically. These bacteria produce inflammatory products, whichpermeate through thin walls of dilated sebum-filled duct. Once in theperifollicular dermis, they trigger the body's own immune defenses (bothacute and granulaomatous) to produce the characteristic inflammatorypapules, pustules and nodules characteristic of inflammatory acne. Theterm “acne” is used herein as a general term to include inflammatorydiseases of the pilosebaceous unit. In the medical field, the specifictype of acne is usually indicated by a modifying term, although the termacne is frequently used alone to designate common acne or acne vulgaris.

Thus, there are four factors that are believed to be the contributors ofacne: (1) Increased sebum production; (2) Comedo formation, in which thefollicular infundibulum hypercornifies, hyperkeratinizes, andhypodesquamates; (3) Colonization of the follicule by anaerobicPropionibacterium, mainly P. acnes; and (4) The host's inflammatoryresponse. The above four factors are interrelated to each other. Sebumis comedogenic and causes inflammation by itself. Propionibacteriumacnes is a relatively slow growing, (typically) obligate anaerobegram-positive bacterium that is linked to the skin condition acne. Ananaerobic organism or anaerobe is any organism that does not requireoxygen for growth. Obligate anaerobes will die when exposed toatmospheric levels of oxygen.

The Propionibacterium has high lipolytic activity and liberates freefatty acids from sebum lipids. The free fatty acids have been shown tocause marked inflammation. The microorganisms also produce otherextracellular enzymes such as proteases and hyaluronidases, andchemotactic factors, which may be important in the inflammatory process.It would thus be advantageous to provide relief from all of the abovefour principal causes of acne.

Rosacea is a common facial dermatitis that currently affects anestimated 13 million Americans. It is a chronic and progressivecutaneous vascular disorder, primarily involving the malar and nasalareas of the face. Rosacea is characterized by flushing, erythema,papules, pustules, telangiectasia, facial edema, ocular lesions, and, inits most advanced and severe form, hyperplasia of tissue and sebaceousglands leading to rhinophyma. Rhinophyma, a florid overgrowth of the tipof the nose with hypervascularity and modularity, is an unusualprogression of rosacea of unknown cause. Ocular lesions are common,including mild conjunctivitis, burning, and grittiness. Blepharitis, themost common ocular manifestation, is a nonulcerative condition of thelid margins. Rosacea most commonly occurs between the ages of 30 to 60,and may be seen in women experiencing hormonal changes associated withmenopause. Women are more frequently affected than men; the most severecases, however, are seen in men. Fair complexioned individuals ofNorthern European descent are most likely to be at risk for rosacea;most appear to be pre-disposed to flushing and blushing.

The cause of rosacea is poorly understood, numerous theories have beenoffered. Hypotheses have included gastrointestinal, psychological,infectious, climatic, and immunological causes, although scientificevidence has not substantiated any of these as primary. Controlledstudies have not demonstrated consistent preponderance ofgastrointestinal symptoms in rosacea patients. Similarly, neither adistinct psychological abnormality nor one pharmacological mechanism hasbeen isolated in rosacea patients. Perhaps the most commonly touted ofthe etiologic theories is based on the presence of Demodex folliculorummites in patients with rosacea; the organism feeds on sebum, and in somecases treatment of demodex infestation has noted improvement in therosacea; however, in a review of 79 biopsies in 1969, Demodexfolliculorum was noted in only 19% of the specimens. A bacterial causefor the disease has been hypothesized, but no consistent findings of onebacterium have been demonstrated. Climate, specifically exposure toextremes of sun and cold, may have an effect on the course of thedisease, but the role of climate in what appears to be a connectivetissue disorder is not clear. An autoimmune process has been suggested,and tissue-fixed immunoglobulins have been reported in patients withchronic inflammation of rosacea, but no other evidence has been found.Other experimental evidence has suggested this disease may represent atype of hypersensitivity reaction. No single hypothesis appears toadequately explain both the vascular changes and the inflammatoryreaction seen in rosacea, leaving the pathogenesis unclear. Morerecently, certain investigators have suggested a connection betweenrosacea and H. pylori, bacteria shown to cause certain gastrointestinalulcers, because symptoms seem to have abated in some ulcer patients alsosuffering rosacea. Nevertheless, the connection between H. pylori androsacea has been questioned. H. Herr, J. Korean Med Sci Oct. 15, 2000;(5):551-4; R. Boni, Schweiz Med Wochenschr Sep. 16, 2000; 130(37):1305-8).

Kang et al. (U.S. Patent Application 20020183399) have recentlyconcluded that rosacea and acne have many common features in their onsetand cure. The topical composition for treating rosacea, which comprisesa combination of an antimicrobial and at least one of (a) ananti-inflammatory and (b) a non-retinoid inhibitor, are very similar fortreating acne, according to Kang, for example. It would thus appearlogical to develop broad-spectrum compositions that can treat both acneand rosacea, although such compositions are still unknown, until now.

Most acne treatments are directed at preventing inflammatory lesions,particularly the larger nodulo-cystic lesions that tend to bedestructive and lead to permanent scarring. In general, visiblecomedones are the only minor cosmetic nuisances and do not lead toinflammatory lesions. Most acne treatment is directed to four areas: (1)Keratinous plugs in sebaceous ducts; (2) Large sebaceous glandsproducing excess sebum; (3) Increased numbers of resident follicularbacteria; and (4) Inflammatory response to chemical mediators passingthrough the follicular wall.

Topical products used to remove comedones are known as comedolytics, themost effective being tretinoin, marketed as a prescription product(Retin A) and by several generic companies. Tretinoin or all-transretinoic acid is the naturally occurring metabolite of Vitamin A.Tretinoin increases epidermal cell turnover, thus causing comedolysisand most importantly prevents the formation of new keratinous plugs.Applications of tretinoin are normally once a day at bedtime. Dryness,stinging and redness sometimes accompany the applications. Importantly,improvement is usually not seen for 6-8 weeks. Adapalene 0.1% (Differin)is a topical retinoid like tretinoin. Available by prescription only,the gel is usually applied once nightly. Side effects include frequentscaling, burning, redness and dryness. Improvement is delayed and is notevident for 4-8 weeks. Sodium sulfacetamide 10%/sulfur 5% (Sulfacet-R)is also available by prescription only. It is a lotion withantibacterial and comedolytic action. As with tretinoin, improvement isseen in 4-8 weeks. Salicylic acid 2% is an over the counter product thatexhibits mild comedolytic activity.

The only products that have anti-sebum activity are estrogens and 13cis-retinoic acid (isotretinoin) and these must be used systemically tobe effective. Isotretinoin (Accutane) is a metabolite of Vitamin Aavailable by prescription only. Isotretinoin is used to treat onlysevere cystic or conglobate acne. Because of its teratogenic properties,birth defects can occur. Isotretinoin is a powerful drug and can elevatetriglycerides, total cholesterol and decrease high-density lipoproteins(HDL). Other side effects include dry skin, dry eyes, itching,headaches, nosebleed, and photosensitivity. It is generally taken for4-5 months to see improvement. Recently, one brand of oral contraceptivehas been approved for the treatment of acne for patients who requestbirth control.

A number of topical and systemic agents are used to lower the number ofbacteria that colonize the follicular duct. These include benzoylperoxide (BP), BP 5%/erythromycin 3% (Benzamycin). BP has antibacterialactivity and drying effects and is available over the counter or byprescription. Moreover, it has been recently reported that benzoylperoxide seems to induce free radical production that can produce skinchanges that qualitatively resemble ultraviolet B damage, e.g.,increases in epidermal thickness, and deleterious changes in elastin andglycosaminoglycans content (Ibbotson, S. H., et al., J. Inves. Derm.,1999, 112: 933-938). In addition, Benzoyl peroxide is highly reactive,and is thus difficult to stabilize in practical compositions. BP isapplied once or twice daily for 1-2 months. BP can produce erythema andpeeling of skin. BP is often tried first for both non-inflammatory andmild inflammatory acne. Other topical antibiotics include clindamycinand erythromycin. These are used as solutions, lotions or gels byprescription only. Usually they are applied once or twice daily andresults are seen in 1-2 months. Azelaic acid 20% (Azelex) also has mildantibacterial effects. Systemic antibiotics include tetracycline and itsanalogs, which are used in low doses for years or until the end of theacne prone years. Most patients with mild inflammatory acne receive acombination of topical antibiotics and tretinoin or other retinoid.Bacterial resistance does occur so antibiotics may be changed or BP issubstituted since resistance does not occur with BP. More severe acnerequires systemic antibiotics and topical retinoid. The most severe mustreceive oral isotretinoin for 4-5 months.

There are no drugs that directly affect the inflammatory acne. Theretinoids do have some anti-inflammatory properties, but these arepoorly described. Topical steroid and even systemic steroids have beenused to abort a severe flare of fulminant acne, but these are limiteduses because of the side effects. Benzoyl peroxide gels are sometimesused as first aid on acne lesions. These function as a “drawingpoultice”, but data supporting this use is not available.

The treatment for acne centers on opening the pore, killing P. acnes,reducing sebum production and regulating inflammatory responses.Retinoids are the agents to reduce sebum production and open the pore.As a topical agent, Differin (adapalene) or Retin-A (tretinoin) is usedfor mild and moderate acne. Isotretinoin, an oral drug, is veryeffective but reserved for the severe and resistant acne because of itsteratogenicity, hepatotoxicity, elevating triglyceride level and otherside effects.

For topical applications, the Food & Drug Administration (FDA) hasapproved the following ingredients for marketing topical acne productsin the USA (Code of Federal Regulations, 21CFR333.310); (1) Resorcinol(2%, in combination only); (2) Resorcinol monoacetate (3%, incombination only); (3) Salicylic acid 0.5 to 2 percent, and (4) Sulfur 3to 10 percent.

Salicylic acid has been used to treat acne for some time. Salicylic aciddries the skin, which helps in acne management, but it also causes skinirritation in perilesional skin areas of acne patients, especiallypatients with sensitive skin, and in some cases the erythema is extreme.Salicylic acid is also pH-sensitive, as in neutralized forms, such assodium salicylate or triethanolamine salicylate; there is a loss ofefficacy due to poor bioavailability. In free acid form, salicylic acidis absorbed rapidly and transported into bloodstream. This is the reasonfor its irritation-causing problems. It would thus be advantageous ifsalicylic acid can be provided in a form that is slow to absorb intodeeper layers of skin for its maximum topical bioavailability andanti-acne efficacy.

Topical and oral antibiotics, especially tetracycline, erythromycin, andclindamycin, are sometimes prescribed for patients with inflammatorypapules and pustules. However, in addition to the undesirability ofantibiotic overuse in general, which can lead to enhance susceptibilityto infection, disadvantages to such treatments include phototoxicity andinteractions with other medications. Other factors that play a role inexacerbating acne, including oil-based cosmetics and some drugs (e.g.,androgenic hormones, high-progestin birth control pills, systemiccorticosteroids, and iodide- and bromide-containing agents) are oftenminimized during acne treatment. Besides the side effects of theantimicrobial agents, development of resistant microorganisms has becomean important issue nowadays. The number of patients harboring resistantP. acnes has been shown to be growing. For this reason, it would beadvantageous to exclude antibiotics and antibacterial agents fromtopical preparations for acne.

For efficacious topical treatments, it would thus be advantageous toinclude the following six-prong provisions to control fundamentalelements that can provide control of both acne and rosacea in a singlecomposition: (1) Control of excess sebum production; (2) Control ofundesirable bacteria and mites; (3) Control of inflammation; (4)Enhanced desquamation of follicular infundibulum cells; (5) Reduction ofirritation from anti-acne and anti-rosacea compositions themselves; and(6) An enhancement of the topical bioavailability of anti-acne andanti-rosacea compositions.

Since the resistance to bacteria is becoming a problem, it would beadvantageous to control bacteria without using an antibacterial agent.Also, salicylic acid is being one of the most favored and inexpensiveingredients to control acne, albeit its irritation causing side effects,it would be advantageous to devise methodologies to increase bothtopical bioavailability and anti-acne efficacy of salicylic acid with areduction in its irritation causing side effects.

The prior art literature abounds with acne and rosacea treatments. FromJanuary 2001 to January 2003 time period over 900 patent applicationswere listed in U.S. patent applications computer database search thatrelated to acne. From 1975 to January 2003, there were over 9000 patentsissued by the U.S. Patents Office that had some reference to acne. Inthe same period, there were over 400 patents that had a reference torosacea. It may also be appreciated that the study and treatment ofrosacea has been a long-time concern of the medical community. Forexample, about 1,000 medical papers have been published on this subject.From these data, it would become obvious that a suitable solution toacne and rosacea problems has not yet been found. A discussion of thepatents and patent applications most pertinent to the present inventionfollows. U.S. Patent Application 20030021855 (Perricone) discloses acneprevention by the topical application of compositions containing analkanolamine such as dimethylaminoethanol, in combination with tyrosineand a sulfur ingredient such as lipoic acid or glutathione. Suchalkanolamines have strong amine odor that is objectionable to consumersfor application on face. Moreover, several such alkanolamines have ahigh pH that can cause irritation. U.S. Patent Application 20030021816(Kang) discloses an immunosuppressant compound, a second activeingredient selected from the group consisting of comedolytics,antibacterials, anti-inflammatory, retinoids, glucocorticoids, andmixtures thereof, and a dermatologically acceptable carrier for acnetreatment. Such immunosuppresants are not readily available for commonuse. U.S. Patent Application 20020192298 (Burrell) relates to the use ofantimicrobial metals, preferably silver for the treatment of acne. It ispreferred that the use of any antimicrobial agents for acne treatment beminimized or eliminated due to development of resistant bacteria. U.S.Patent Application 20020172672 (Sieberg) is directed to the use ofserine proteases, either alone or in combination with a retinoidcompound in a pharmaceutical or cosmetic composition for acne treatment.Such enzyme preparations can cause serious skin allergy in some humans.U.S. Patent Application 20020155180 (Goodman) discloses treatment ofacne that comprises topically applying an effective amount of a sawpalmetto berry extract and one or more constituents that enhancepenetration of the extract into hair follicle sebaceous glands. Thisdisclosure is specific to one ingredient, hence of limited application.U.S. Patent Application 20020151527 (Wiegand) discloses a method forreducing the number and severity of acne lesions comprisingadministering a sensory regimen to down regulate the activity of thehypothalamus-pituitary-adrenal axis, in combination with theadministration of a topical anti-acne composition comprising ananti-acne agent selected from salicylic acid, sulfur, lactic acid,glycolic acid, pyruvic acid, urea, resorcinol, N-acetylcysteine,retinoic acid, benzoyl peroxide, octopirox, triclosan, azelaic acid,phenoxyethanol, phenoxypropanol, flavinoids, derivatives thereof, andmixtures thereof. The problems of salicylic acid irritation and lowtopical bioavailability and the use of antibacterials are still noteliminated by Wiegand. U.S. Patent Application 20010056071 (Pelicchia)discloses the application of antioxidant resveratrol for acne treatment.U.S. Pat. No. 6,451,773 (Oester et al.) discloses a combination ofchitosan with azelaic acid, benzoyl peroxide, retinoic acid, salicylicacid, or mixtures thereof, for the treatment of acne. Chitosan is usedas a film-forming agent for topical application of other activeingredients for better adhesion to skin surface. While topicalbioavailability is enhanced, the skin irritation and other problems ofsalicylic acid and azelaic acid use are not reduced. U.S. Pat. No.6,440,994 (Sanders) discloses acne treatment using a mixture ofantihistamines and anti-inflammatory agents. This does not provide amultifaceted treatment objective. U.S. Pat. No. 6,436,417 (Singh)discloses solubilized forms of salicylic acid for acne treatment. Suchsolubilized forms absorb more quickly, reaching bloodstream at a fasterrate. Both the topical anti-acne efficacy may be lower and skinirritation may be higher for such compositions. U.S. Pat. No. 6,433,024(Popp et al.) discloses topical anti-acne compositions based on benzoylperoxide, an alpha hydroxy acid, a moisturizer, an isosorbide and adetergent. These compositions contain several skin irritatingingredients. U.S. Pat. No. 6,365,623 (Perricone) discloses one preferredembodiment that contains a combination of lipoic acid, an alpha-hydroxyacid, and dimethylaminoalcohol. Lipoic acid is also claimed to curerosacea (U.S. Pat. No. 6,472,432; Perricone). U.S. Pat. No. 6,262,117(Sefton) discloses acne treatment based on a combination of benzoylperoxide and azelaic acid. The poor stability of benzoyl peroxide andthe skin irritation of either benzoyl peroxide or azelaic acid are stillunsolved in Sefton disclosure. U.S. Pat. No. 6,168,798 (O'Halloran etal.) discloses an alcoholic solution of salicylic acid and salicylatesfor acne treatment. The rapid absorption of such clear solutions intoskin would reduce the topical bioavailability of the active ingredientsin such compositions. U.S. Pat. No. 5,989,523 (Fitzjarrell et al.)discloses a topical spray comprising niacinamide, Aloe Vera extract andNaPCA in a water carrier base. U.S. Pat. No. 5,910,312 (Fried) disclosesan anti-acne composition comprising benzoyl peroxide, salicylic acid,and a vasoconstrictor in an inert carrier. Benzoyl peroxide has beensuggested for treating acne vulgaris. (See U.S. Pat. No. 4,387,107.) Formany years, benzoyl peroxide has been proven to be a particularlypowerful keratolytic and anti-seborrhic agent, as well as being endowedwith antibacterial properties. Topical benzoyl peroxide compositions,including a vehicle to enhance the efficacy thereof, are known (See U.S.Pat. No. 4,411,893). Topical compositions of benzoyl peroxidecombination with antibiotics are also known. (See U.S. Pat. Nos.4,407,794; 4,692,329 and 4,387,107). The problems of skin irritationfrom benzoyl peroxide or salicylic acid, and the chemical instabilityand reactivity of benzoyl peroxide are still not solved; complex,dual-chamber delivery systems (such as U.S. Pat. No. 6,462,025;Vishnupad and U.S. Pat. No. 6,448,233; LaFevre et al.) have beendisclosed.

Rosacea is, while rare among colored races, common among races with alight-colored skin, especially among white races, and many cases occuramong them. It is divided according to the symptoms into the firstdegree (telangiectatic rosacea on the forehead, cheeks, dorsum nasi),the second degree (acne rosacea, coexistence of follicular papules andpustules), and the third degree (rhinophyma, dark red tumor and dilatedpore on apex nasi). It starts with facial flush (redness) and eventuallyinvolves serious impairment of appearance, developing papules, pustules,rhinophyma and tumor on apex nasi, it is also accompanied by seborrheaor enhancement of feeling of heat on the face due to emotional stress orchange of environmental temperature. Thus, these symptoms give a patientmental and physical suffering. For the time being, the real cause ofrosacea is unknown (Hifuka Chirya Handbook, pp. 380-381, Nanzando (1987)and Gerd Plewing, Albert M. Kligman, ACNE and ROSACEA, 2nd, CompletelyRevised and Enlarged Edition, pp. 431-454, Springer-Verlag (1993)).Rosacea is apt to be confused with acne. Rosacea, which can coexist withacne, essentially differs from acne. It is characterized by facial flushdue to vascularization and proceeds with acne rosacea and tumor on apexnasi. The etiology of rosacea is not fully known, however, at least fourfactors or co-factors have been suggested. The first of these isendocrine in that the disease occurs most frequently in women betweenthe ages of thirty and fifty. As such, one definite type of rosacea isbelieved to have a hormonal basis. A second factor is vasomotorliability, believed to have some connection with menopause, which bringsabout an impairment of normal or consistent flow of blood to the faceand its capillaries. Therein, excessive flow of blood to the face, i.e.,the well-known “hot flashes” of menopause, is believed to constitute afactor in the disease and its pathogenesis. More particularly, it hasbeen proven that increased skin temperature, as occurs in facialflushing, increases susceptibility to the condition. Rosacea has alsobeen observed as a side effect or immune response to the use of certaincortisone products, which can bring about a severe form of thecondition. Finally, pathology analysis of the expressed contents ofinflamed pustule follicle of the nose in acute rosacea has demonstratedthe existence of demodices, which is a signature of the ectoparasitedemodex folliculorum. Accordingly, in such cases, a specific externalpathogenic factor is evident. This factor is not present in other formsof acne, e.g., acne vulgaris.

However, the information available so far does establish that both acneand rosacea are interrelated, and hence a common treatment for bothwould be highly desirable.

Relative to rosacea treatment compositions, U.S. Pat. Nos. 6,352,724 and5,654,013 (Taylor et al.) discloses rubbing common salt (Sodiumchloride). Sodium chloride is the subject of additional disclosures forthe treatment of both acne and rosacea (U.S. Pat. No. 4,443,442 toSkillern; U.S. Pat. No. 3,867,522 to Kligman). However, such treatmentsonly work by a single biochemical mechanism, that of abrasion anddebridement of the affected skin. Also, once the debridement iscompleted, the affected skin will feel pain, since it will be equivalentto “adding salt to injury”. U.S. Pat. No. 6,174,534 (Richard et al.)provides a composition that contains long chain fatty acids for rosaceatreatment. Although such composition may be suitable for rosacea, suchfatty acids may actually exacerbate acne due to excess sebum-likeactivity from such fatty acids. U.S. Pat. No. 6,136,806 (Hittel)discloses certain synthetic organic molecules for rosacea treatment thatare not commonly available, or available by prescription only in certaincountries. U.S. Pat. Nos. 6,133,310 (Parks) and 5,952,372 (McDaniel)disclose the application of Invermectin in the treatment of rosacea.This ingredient has also been used frequently for the treatment of acne.Invermectin, however, provides relief by a single biochemical mechanism,not a six-prong approach. Moreover, Invermectin is not commonlyavailable. U.S. Pat. No. 5,972,993 (Ptchelintsev) discloses theapplication of certain antioxidants for the treatment of rosacea. Thistreatment is thus based only on a single approach of anti-inflammatoryaction of such antioxidants. U.S. Pat. No. 5,667,790 (Sellers) disclosesthe application of aluminum salts for acne and rosacea treatment. Suchaluminum salts only block the exudation of sebum and provide reliefprobably by astringent action. Their long-term use can actually causeadditional inflammatory response. U.S. Pat. No. 5,885,595 (Corey)discloses esters of retinal for acne and rosacea treatment. U.S. PatentApplication 20020013361 (Perricone) claims the use of lipoic acid. Sincelipoic acid is an antioxidant, it probably works by anti-inflammatorybiochemical mechanism, thus constituting just one-prong treatment. U.S.patent applications 20020172719, 20020054918, and 20020041901 (Murad)disclose pharmaceutical composition and methods for the cleansing ofskin to facilitate the prevention, treatment, and management of skinconditions that include rosacea and acne by a composition that includesa hydroxy acid or tannic acid to exfoliate a portion of the skin,stabilized hydrogen peroxide to facilitate cleansing of the skin, and anantimicrobial agent to inhibit or reduce microorganisms on the skin.Since the overuse of antimicrobial agents can cause further problems, asmentioned earlier, Murad inventions are thus of limited application, oreven to be possibly avoided for any long-term rosacea and acne treatmentregimen.

It is thus both surprising and unexpected that the compositions of thepresent invention relieve the symptoms of acne and also rosacea. Theexact mechanism of this action is not well understood at this time.However, this does not reduce the significance or utility of the presentinvention for consumer applications.

Thornfeldt (U.S. Pat. No. 4,978,676) disclosed topical application ofaloesin for the treatment of viral tumors/diseases, hemorrhoids, andbullous skin diseases.

Mazzio et al (U.S. patent application Ser. No. 2004185123) disclose atopical herbal formulation for preventing and/or treating dyshidrosis(pompholyx), non-responsive to topical steroids. The formulation mayalso be used to treat contact dermatitis, eczema, palmoplantarpustulosis and skin infections incurred by invasive pathogens such asmold, fungus and bacteria. The formulation is comprised of plantextracts and niacin, that when combined yield an effective multi-facetedpharmaceutical approach to treating dry skin disorders. The activeingredients within the formula include a combination of dry, aqueous,acid and alcohol extracts of black walnut hull (Ouglans Nigra), wormwood(Artemisia Absinthium), tumeric rhizome (Curcuma Longa), garlic (Alliumsativum), chamomile (Matricaria Chamomile), licorice root (GlycyrrhizaGlabra), St. Johns wort (Hypericum perforatum), aloe vera, niacin andherbal anti-bacterial agents.

The present inventor hypothesizes possible mechanism(s) for anti-acneactivity of the present invention. Acne is caused, among other factors,by Propionibacterium acnes. Most bacteria are greatly dependent on iron(in Fe3+ state) for their metabolic activity. This Fe demand is greaterthat Fe requirements of normal human cells. The bacterial iron transporthas been extensively studies in the prior art, for example Nielands etal. [Adv. Inotg. Biochem., 5, 137 (1983); Struct. Bonding (Berlin), 58,1 (1984)]. The agents responsible for iron transport into and withinbacteria have been extensively studied, and many structural and chemicaldetails have been firmly established. The problem is that iron is notspontaneously available to oxic (aerobic) organisms in an aqueousenvironment because of the very low solubility of ferric hydroxide (pKabout 38). Thus Fe3+ ions at a pH of about 7 have a molar concentrationof only about 10(−18), and simple diffusion into cells could neversuffice to supply their needs. Indeed, simple inward diffusion would notoccur, since iron is already more concentrated than this in the livingcell. Therefore special chelating agents called “siderophores” areproduced by bacteria and ejected into their environment to gather ironand transport it through the cell wall into the cell. In some cases itappears that the chelator at the cell wall releases iron and it passesthrough alone, whereas in others the entire complex enters the cell.

The siderophores are rather diverse chemically but have in common theuse of chelating, oxygen-donor type ligands. A very large number ofsiderophores that have been characterized employ hydroxamate moieties,—CO—N—O(−), as the ligands. The structure of a siderophore, called a“ferrichrome” consists of a cyclic hexapeptide in which three successiveamino acid residues have side chains ending in hydroxamate groups.

Another type of siderophore, especially common in prokaryotes such asenteric bacteria is called an “enterobactin”; the ligating units arecatecholate anions that also chelate very effectively [Raymond et al.,J. Am. Chem. Soc., 107, 6920 (1985)].

Iron-Sulfur proteins are relatively low molecular weight compoundsconsisting of peptide chains bound though cysteine sulfur atoms to redoxcenters that consist either of one iron atom or a cluster of iron andsulfur atoms, the latter often being called “inorganic” sulfur atoms todistinguish them from the sulfur atoms of the cysteine residues. Theterm “rubredoxin” is used for those with one iron atom, while thosecontaining clusters are called “ferredoxins”.

Rubredoxins are found in anoxic (anaerobic) bacteria where they arebelieved to participate in biological redox reactions. They arerelatively low molecular weight proteins (about 6000 amu) containingonly one iron atom. In the best-characterized rubredoxin, from thebacterium Clostridium pasturianum, the iron atom, which is normally inthe III oxidation state, is surrounded by a distorted tetrahedron ofcysteinyl sulfur atoms. The Fe—S distances range from 2.24 to 2.33Angstroms (A), and the S—Fe—S angles from 104 to 114 degrees. When theFe (III) is reduced to Fe (II) there is a slight (0.05 A) increase inthe Fe—S distances. However, Mossbauer spectroscopy shows that Fe isactually present both in (III) and (II) oxidation states. Ferredoxinsare also relatively small proteins (about 6000-12000 amu) in which theredox centers, clusters of two, three, or four iron atoms, each with anequal number of sulfur atoms are held in place by bonds from cysteinesulfur atoms to iron.

From the above discussion it can be seen that a distortion ofrubredoxin, ferredoxin, ferrichrome siderophore, and enterobactinsiderophore can cause a disruption of bacterial metabolism. Thus, thebacteria may not be killed via the antibacterial action, but theirmultiplication by cell division may be hampered for their furthergrowth.

In an unexpected and surprising discovery it has now been found that thecompositions of the present invention bind with rubredoxin moiety ofPrionionibacterium acnes. When this bound form of rubredoxin enters theacne bacterium the cellular redox functions are inhibited. This causesthe acne bacterium to cease its metabolic activity. However, this isonly one mechanism for anti acne activity of the present invention.There are several other possible modes of anti-acne action, as mentionedabove, which are yet unknown for the benefits rendered by the presentinvention. As stated before, this should not preclude the utility ofthis invention.

Control of Dark Spots. Inhibition of Phenylalanine Hydroxylase andPhenylalanine Transaminase.

The biosynthetic pathways from shikimic acid leading to the formation ofmelanin are summarized in FIG. 1 that will be used as a reference forsubsequent discussions.

FIG. 1.

Phenylalanine hydroxylase is responsible for the first step in theconversion of phenylalanine into tyrosine. Tyrosine is required for theproduction of melanin, which gives color to hair and skin. Phenylalaninehydroxylase must work in combination with tetrahydrobiopterin to performthis function. Phenylalanine hydroxylase contains iron in its activesite, and tetrahydrobiopterin is required in proximity to this activesite.

It is both surprising and unexpected that compositions of the presentinvention inhibit phenylalanine hydroxylase. Although the mechanism ofthis inhibition is not fully clear at this time, it is theorized thatthe binding of iron metal at the active site of Phenylalaninehydroxylase (Reaction Step 8, FIG. 6) and/or binding with Fe attetrahydrobiopterin could be the cause for this effect.

Control of Dark Spots. Inhibition of Tyrosine Transaminase andMonophenol Monooxygenase (Tyrosinase).

Tyrosinase [EC:1.14.18.1] is a complex group of copper monooxygenasesthat catalyses the hydroxylation of monophenols and the oxidation ofortho-diphenols to ortho-quinones. This enzyme, found in prokaryotes andeukaryotes, is involved in the formation of pigments such as melaninsand other polyphenolic compounds. Tyrosinase binds two copper ions (CuAand CuB). It has been shown that three conserved histidine residues bindeach of the two copper ions. The regions around these copper-bindingligands are well conserved and also shared by some hemocyanins, whichare copper-containing oxugen carriers from the hemolymph of manymollusks and arthropods. At least two peoteins related to tyrosinase areknown to exist in mammals, and include TRP-1, which is responsible forthe conversion of 5,6-dihydroxyindole-2-carboxylic acid (DHICA) toindole-5,6-quinone-2-carboxylic acid; and TRP-2, which is themelanogenic enzyme DOPAchrome tautomerase [EC:5.3.3.12] that catalyzesthe conversion of DOPAchrome to DHICA. TRP-2 differs from tyrosinasesand TRP-1 in that it binds two zinc ions instead of copper.

The inhibition of melanin synthesis can thus be achieved via severalpathways, including the inhibition of tyrosine transaminase (inhibitionof amination of hydroxyphenyl Pyruvate or phenyl Pyruvate (Step [7]and/or [4], FIG. 1), which leads to eventual inhibition of tyrosinebiosynthesis. The melanin synthesis can also be blocked by theinhibition of monophenyl monooxygenase (EC 1.14.18.1), which convertstyrosine into dopaquinone via the intermediacy of dopa. In a surprisingand unexpected discovery, the compositions of the present inventioninhibit both tyrosine transaminase and monophenyl monooxygenase. Theprecise mechanism of this inhibition is not known at this time, but itis hypothesized that the compositions of the present invention bind withFe in the active-site of monophenyl monooxygenase. Regardless of theactual biochemical mechanism the importance of this invention remainsunexpected and novel.

Skin Brightening and Antiwrinkle-Antiaging Applications.

The compositions of the present invention provide an unexpectedinhibition of MMP, tyrosinase, and tyrosine biosynthesis enzymes. Thedown-regulation of MMP leads to reduced degradation of connective issuesuch as collagen and fibrin. This results in increased suppleness ofskin, leading to reduced visible skin wrinkles from aging. The decreasedbiosynthesis of tyrosine and dopa, and inhibition of Tyrosinase andtyrosine precursor enzymes leads to skin brightening effects, all ofwhich are both surprising and unexpected when taken as a group of suchdesirable benefits. In normal practice, such group of desirable benefitsis usually achievable only from a combination of several ingredients.The compounds providing good skin brightening are of formula (XIV), andisomers and salts thereof:

Wound Healing Applications.

The compositions of the present invention provide an unexpected woundhealing benefit with little scar tissue formation or skin pigmentdiscoloration.

The entire wound healing process is a complex series of events thatbegins at the moment of injury and can continue for months to years.This overview will help in identifying the various stages of woundhealing. [0086] I. Inflammatory Phase. A) Immediate to 2-5 days; B)Hemostasis, (i) Vasoconstriction, (ii) Platelet aggregation, and (iii)Thromboplastin makes clot; C) Inflammation, (i) Vasodilation, (ii)Phagocytosis. [0087] II. Proliferative Phase. A) 2 days to 3 weeks; B)Granulation, (i) Fibroblasts lay bed of collagen, (ii) Fills defect andproduces new capillaries; C) Contraction, [0088] (i) Wound edges pulltogether to reduce defect; D) Epithelialization, (i) Crosses moistsurface, (ii) Cell travel about 3 cm from point of origin in alldirections. [0089] III. Remodeling Phase. A) 3 weeks to 2 years; B) Newcollagen forms which increases tensile strength to wounds; C) Scartissue is only 80 percent as strong as original tissue.

Wound healing, or wound repair, is the body's natural process ofregenerating dermal and epidermal tissue. When an individual is wounded,a set of events takes place in a predictable fashion to repair thedamage. These events overlap in time and must be artificiallycategorized into separate steps: the inflammatory, proliferative, andmaturation phases. In the inflammatory phase, bacteria and debris arephagocytized and removed and factors are released that cause themigration and division of cells involved in the proliferative phase. Theproliferative phase is characterized by angiogenesis, collagendeposition, granulation tissue formation, epithelialization, and woundcontraction. In angiogenesis, new blood vessels grow from endothelialcells. In fibroplasia and granulation tissue formation, fibroblasts growand form a new, provisional extracellular matrix (ECM) by excretingcollagen and fibronectin. In epithelialization, epithelial cells crawlacross the wound bed to cover it. In contraction, the wound is madesmaller by the action of myofibroblasts, which establish a grip on thewound edges and contract themselves using a mechanism similar to that insmooth muscle cells. When the cells' roles are close to complete,unneeded cells undergo apoptosis. In the maturation and remodelingphase, collagen is remodeled and realigned along tension lines and cellsthat are no longer needed are removed by apoptosis.

In the inflammatory phase, clotting takes place in order to obtainhemostasis, or stop blood loss, and various factors are released toattract cells that phagocytize debris, bacteria, and damaged tissue andrelease factors that initiate the proliferative phase of wound healing.When tissue is first wounded, blood comes in contact with collagen,triggering blood platelets to begin secreting inflammatory factors.Platelets also express glycoproteins on their cell membranes that allowthem to stick to one another and to aggregate, forming a mass. Fibrinand fibronectin cross-link together and form a plug that traps proteinsand particles and prevents further blood loss. This fibrin-fibronectinplug is also the main structural support for the wound until collagen isdeposited. Migratory cells use this plug as a matrix to crawl across,and platelets adhere to it and secrete factors. The clot is eventuallylysed and replaced with granulation tissue and then later with collagen.Platelets, the cells present in the highest numbers shortly afterwounding, release a number of factors into the blood, including ECMproteins and cytokines, including growth factors. Growth factorsstimulate cells to speed their rate of division. Platelets also releaseother proinflammatory factors like serotonin, brakykinin,prostaglandins, prostacyclin, thromboxane, and histamine, which serve anumber of purposes, including to increase cell proliferation andmigration to the area and to cause blood vessels to become dilated andporous.

Contrary to common belief, the use of any anti-inflammatory agentsduring the early stages of would-healing process is not desirable. Onthe same note, the over-expression of MMP-13 should be controlled fromthe onset of wound healing process to avoid apoptosis of newly formedconnective tissue. Both connective tissue forming agents andanti-inflammatory agents are beneficial during the later stages of woundhealing.

The exact mechanism of topical wound healing by the compositions of thepresent invention is believed to be due to the inhibition of HemeOxidase, the exact nature if which is not yet known. However, thisshould not preclude the practical utility of the present invention intopical wound healing applications.

Treatment of Dandruff.

Recently, identification of Malassezia (formerly known as Pityrosporum,is a genus of related fungi, classified as yeasts; naturally found onthe skin surfaces of many animals including humans) has been aided bythe application of molecular or DNA based techniques. Theseinvestigations show that the Malassezia species causing most skindisease in humans, including the most common cause of dandruff andseborrhoeic dermatitis, is M. globosa (though M. restricta is alsoinvolved). The skin rash of tinea versicolor(pityriasis versicolor) isalso due to infection by this fungus. So far, 10 species of Malasseziahave been identified: M. furfur, M. pachydermatis, M. globosa, M.restricta, M. slooffiae, M. sympodialis, M. nana, M. yamatoensis, M.dermatis, and M. obtuse.

As the fungus requires fat to grow, it is most common in areas with manysebaceous glands: on the scalp, face, and upper part of the body. Whenthe fungus grows too rapidly, the natural renewal of cells is disturbedand dandruff appears with itching (a similar process may also occur withother fungi or bacteria). The number of specimens of M. globosa on ahuman head can be up to ten million.

The compounds of the present invention have shown high activity againstdandruff and seborrhea causing organisms.
